foaming and biodegradable detergents made speci-
fically for scrubber-driers. The use of other chemical
products (such as sodium hypochlorite, oxidisers,
solvents or hydrocarbons) may damage or destroy
the machine.
• Follow the safety regulations specified in the relati-
ve section and indicated on the detergent container.
• Contact the machine manufacturer to obtain a com-
plete list of available and suitable detergents.
☞ Always add the detergent after filling the tank with
water to prevent foam from being created inside.
• Do not leave the water hose unattended and insert
it completely into the tank: the hose might move and
get sensitive parts of the machine wet.
Close the tank with its plug...
To drain:
• Unscrew the cock.
• Close the drainage plug firmly.

DRAINING THE RECOVERY TANK
The dirty water must be drained in accordance with
national regulations.
The user is completely responsible for ensuring com-
pliance with such rules.
After the detergent solution is finished, always empty
the recovery tank before filling it again.
In general, the recovery tank can be emptied whene-
ver required, and even during intermediate phases of
the work cycle.
The recovery tank volume is higher than the deter-
gent solution volume, therefore a potentially dan-
gerous situation for the suction motor should never
occur. In any case, a safety float turns off the suction
motor if the dirty liquid level is too high.
• If water or foam starts leaking from under the
tanks for any reason, immediately turn off the suction
motor and empty the recovery tank.
To drain the tank:
Drive the machine to a suitable location to drain the
dirty water and preferably near a toilet or a sewer
drain (comply with the national regulations for waste
water disposal).
Turn off the machine and remove the key from the
panel.
Detach the drain hose from the hook and, keeping it
high, unscrew the plug.
Lower the drain hose toward the selected drainage
point.
The emptying operation can be interrupted quickly
and whenever required just by raising the drain hose.
Check how much dirt is still in the tank and, if neces-
sary, wash it inside through the inspection hole by
unscrewing the rear window .
Fully tighten the drain hose with the screw plug and
hang it on the support behind the machine. The drain
hose plug must be airtight, otherwise the subsequent
pressure loss will reduce drying efficiency.

DRIVING THE MACHINE
Check connection between the power and battery
connectors, located under the control panel.
Put the ignition key in and turn it.
Check battery charge status via the control unit and,
if sufficient, select the running speed wanted, operate
the brush control key and the suction control key. Now
open the solution cock by lowering the detergent do-
sage lever which is at the back of the machine, lower
the suction unit by lowering the squeegee control le-
vel, lower the washing unit, levering with your foot on
the brush plate control lever.
Move forwards, pulling the forward lever up . Re-
member to lift the floor cleaner before reversing to
avoid damaging it.

WORK METHOD
6.7.1. PREPARATION AND WARNINGS
Remove any loose solid residue from the surface
to be treated (using suitable tools, such as vacuum
cleaners, sweepers, etc.). It this is not done, the solid
dirt might prevent the squeegee from operating cor-
rectly, reducing drying efficiency.
This machine can driven only by trained personnel.
6.7.2. OPERATING CONTROLS
• Battery charge control: the sequence of lights pro-
gressively turns off until the battery is discharged .
When the red light turns on, turn off the brush motor,
close the solution supply, finish drying the small resi-
dual moisture and go to the battery charging area to
charge the battery.
• The batteries may be irreparably damaged if the
residual charge level drops too low (see the battery
operating manual). Do not force the battery dischar-
ge beyond the safety limits, turning the key off and
on or in any other manner.
• When an abnormal situation occurs, such as when
the machine doesn't have enough power and the
safety devices don't trip, stop immediately: follow
the instructions in the troubleshooting section and
contact a specialised worker to check the discharge
control devices.
6.7.3. DIRECT SCRUBBING OR FOR SLIGHTLY
DIRTY SURFACES
Scrubbing and drying in a single pass.
Prepare the machine as previously described.
Check connection between the power and battery
connectors, located under the control panel.
Put the ignition key in and turn it.
Check battery charge status via the control unit and,
if sufficient, select the running speed wanted, opera-
te the brush control key and the suction control key.
Now open the solution cock by lowering the deter-
gent dosage lever which is at the back of the machi-
ne, lower the suction unit by lowering the squeegee
